Mump 0712 20 Z Balancing

Driveshafts are dynamically balanced just like car tires. Inland Empire Driveline spins the shaft very fast, finds the light side, and welds weight to the shaft. Before welding, the shaft is spun with the weight tied in place to check for vibration. Remember, dynamic balancing isn't foolproof. Because driveshafts are subjected to stress issues, their dynamics can change after balancing.
